Stage that occurs at end of 5th week. Comprised of mesodermal tissue, not functional until the end of the 8th week. Kidneys start in the pelvis and descend into the abdomen.
What does the parenchyma consist of?
Renal cortex and medulla
What is the renal cortex?
The outer area that contains the renal corpuscle and convuluted tubules of the nephron
What is the medulla?
The inner portion of the parenchyma which contains the loops of Henle
What are the columns of Bertin?
Bands of cortical tissue that seperate the medullary pyramids
What is the renal lobe?
A single pyramid bordered on both sides by the interlobar arteries and veins, with cortical tissue at its base.
What is the renal sinus?
The central portion of the kidney. Contains the collecting system, composed of the minor and major calyces and the renal pelvis
4 layers of the urinary bladder
mucosa, submucosa, muscularis, and outer serosa

What does the renal corpuscle consist of?
(Malphigian body)
Consists of glomerulus and glomerular capsule (Bowman's capsule)
Blood flow through the kidney-outside to w/in

At the kidney, distal is at the aorta
Hyper to hypo
